This novel synthetic method has the advantages of high yields, short reaction times, low cost and availability of the catalyst, solvent-free reaction conditions, simplicity and easy work-up compared to the conventional methods reported in the literature.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Shirini, Farhad and Rad-Moghadam, Kurosh and Naghdi, Tahereh}, year={2024}, month={Feb.}, keywords={5-dimethylhydantoin.
